ChamberArt1000 Piece Premium Jigsaw Puzzles Golden Sunflower A-1158

Q: It says the size of the box, but what's the size of the finished puzzle?

Finished size would be 73.5 x 51 cm (28.9 x 20 in)

Q: Is this metallic? 금장?

Sorry, but this seems a normal puzzle. We searched through a website and A-1003 seems to be the one with metallic puzzle.

Q: Are the puzzle pieces lettered on the back?

No, they are not lettered or numbered on the back. I couldn't complete the puzzle because of the extra pieces, especially the extra edge pieces. I can't recommend this puzzle, which is sad because I really love "The Kiss" painting. Hope this helps. Have a great day.
